Bug when entering custom heart rate zones

[SunsetRunner]

I tried to enter my custom heart rate zones on my Samsung S9 and when I enter upper limit I can press next to enter lower limit and when I enter lower limit there is no way to hit done so I can't exit properly and when I hit back it just unchecks custom zones and I still have none. It is a bug in the code but there is no easy way to report it!

I just reported the exact same issue. I have an Android phone, I can enter min and max, then hit Done in the top right corner, but it exits the setting without saving it, so when I reopen it my setting is gone. The same is happening on the web too, Settings -> Personal Info -> Heart Rate Zones (bottom), I set it to Custom and enter min and max, when I save a green success notification appears, but my setting is reverted back to Default.

My issue has been resolved. I didn't do anything, it got fixed by itself the next day, weird, but it works again.
